I just changed out the seals and dust cover, along with the suspension fluid on my 08 Fox 32 Float 140 fork. Everything went smooth, replaced the seals and put new fluid in. Tightened everything down and then sat on the bike and when I pulled the bars up ( like poopin a wheelie) the fork sort of knocked. I noticed that the lowers slide down about a 1/4 of an inch when I lift the front end up. Is this normal and I just didn't notice it before or did I do something wrong?
